Pronunciation

  • UK: /kənˈɡlɒm.(ə.)ɹɪt/, /kənˈɡlɒm.əˌɹeɪt/[1]
  • US: /kənˈɡlɑ.mɚ.ət/, /kənˈɡlɑm.ɹət/[1]

Etymology

It is borrowed from Latin conglomerātus, the past participle of conglomerō (“to roll together, heap up”),[2][3][4][5][6] from com- (“with, together”) and glomerō (“to wind into a ball, gather”), from glomus (“ball, as of yarn”).[3][4][7][5] Etymonline suggests that glomus may come from Proto-Indo-European *glem-, the root of glebe,[3] and Hoad relates it to globus, the source of globe.[8] The verb, recorded from 1596, is from the participial stem of the same Latin verb,[2][4][6] and the noun grew out of the adjective.[3][4]

Earliest recorded meaning

Gathered together into a rounded mass: 1572, as a past participle, in John Bossewell's Workes of Armorie;[2][4][5] Etymonline dates it to the 1570s.[3] The Shorter Oxford and the Oxford Dictionary of English put the adjective in late Middle English.[6][9]

Semantic evolution

From 1666 physiologists called glands of complex structure conglomerate, as opposed to conglobate ones,[2] and Johnson (1755) gave this sense first.[10] Geologists used it from the early 19th century for rock made of rounded fragments cemented together: the OED dates the adjective to 1815 and the noun to 1818,[2][5] Etymonline the noun to 1809.[3] The figurative sense, a mixture of unrelated elements, is from 1837 in the OED and 1831 in Etymonline.[2][3] The business sense, a large corporation formed from diverse companies, is the latest: Barnhart dates it to 1961,[4] Etymonline to 1963, as short for conglomerate corporation,[3] and the OED to 1967.[2] The verb meant to heap together from 1596;[2] Cockeram's dictionary (1623) has it for winding thread into a ball, and the intransitive sense, to cluster together, is from 1642.[2][5] The noun conglomeration is recorded from 1626, in Bacon's Sylva Sylvarum.[4]
